Don't LED lamp power line magnetic field can be converted into electrical energy

Do not insert the power line, LED lighting will send a shining light! Yesterday (13), in the Southeast University innovation laboratory Xian college, Department of electronic engineering students majoring in Electronic Science and technology Ni Linyi showed a power function of wireless transmission is magic. In just the end of 2014 in Jiangsu Province Undergraduate Electronic Design Contest, this set of convenient and efficient equipment to obtain good results in the first prize. The winner was a celebrated "inventor", during the University, he obtained four patents.

"Power wireless transmission principle is very simple, is the electromagnetic conversion." Ni Linyi introduced, the transmitting coil of the direct current into a magnetic field and transmitted, and distance from the receiving coil half meter outside the "capture" of the magnetic field, and converted into electrical energy transmission to LED lighting, lighting natural lights. Of course, in the process of conversion, transmission, power will inevitably be some loss. How to minimize the loss, improve power conversion efficiency, become the key points in the design. "Because the circuit design through accurate analysis of this set of equipment, energy conversion rate is as high as 67%." In the careful guidance of school Zhang Zhipeng, Cao Chengwei teacher, Ni Linyi, Sha Yangyang, Li Youjian three students through repeated tests, finally won the first prize in 2014 in Jiangsu Province Undergraduate Electronic Design contest.

"Modern power devices bring great convenience to life, but as the cobwebs of the wire is also a headache." Ni Linyi introduced the wireless power transmission can solve this problem, household appliances can get rid of "small tail", the electric toy for children have frequently change the battery. People can also rest assured that the wireless power transmission is the use of electromagnetic conversion principle, the human response to the magnetic field almost no, this system does not affect human health.
